  1. 1

    Put water in a pot and boil.

  2. 2

    Open all the tools on the Swiss Army Knife and drop into the boiling water. The boiling water will loosen the grime that has built up on the knife.

  3. 3

    Take the boiling pot of water off the heat after the knife has been it for one minute and pour out the hot water.

  4. 4

    Add warm water to the pot to cool off the Swiss Army Knife. Adding cold water could crack the plastic handle because of temperature shock.

  5. 5

    Remove the knife from the warm water and use a toothbrush to remove any grime still on the knife.

  6. 6

    Coat the knife blades with cooking oil after the knife has been air dried. Rub off the excess oil with a paper towel.

Tips and warnings

  • Handle the knife carefully after taking it out of hot water as the plastic handle could be soft. It will harden again as the knife cools.
  • Always be careful when handling a knife with open blades.
